Introduction to Volcanoes & Volcanology

These presentations (in Microsoft PowerPoint) are made available solely for the use of students in GE151: Introduction to Volcanoes & Volcanology, at Colby College. The PowerPoint files are the actual presentations made in class, sometimes augmented slightly to enhance the materials. However, nothing of substance will be added to materials once they have been presented in class without notifying the entire class that such a change has been made.

Copies of all in-class handouts are accessible as pdf files.

In order to view the PowerPoint presentations, you will need to download them onto a computer capable of running Microsoft PowerPoint. Colby users not having this software may download it from the general server.

The background image on this view is of a pahoehoe lava flow onto the beach on the NE base of Fernandina Island, in the Galapagos Islands of Ecuador.

PLEASE NOTE that these materials will DOWNLOAD to your selected download folder. They will not automatically open in your browser or on the desk-top, unless that is your own default setting.
These also cannot be downloaded on library computers or other college machines with restricted write access.
